■ Speaker types
Front left and right speakers (FL and FR)
The front speakers are used for the main source sound plus
effect sounds. Place these speakers at an equal distance from
the ideal listening position. The distance of each speaker
from each side of the video monitor should be the same.
Center speaker (C)
The center speaker is for the center channel sounds
(dialog, vocals, etc.). If for some reason it is not practical
to use a center speaker, you can do without it. Best results,
however, are obtained with the full system.
Surround left and right speakers (SL and SR)
The surround speakers are used for effect and surround
sounds.
For 5.1-channel speaker layout, place these speakers
farther back compared with the placement in the 7.1-
channel speaker layout.
Surround back left and right speakers (SBL and
SBR) /Surround back speaker (SB)
The surround back speakers supplement the surround
speakers and provide more realistic front-to-back
transitions.
For 6.1-channel speaker layout, surround back left and
right channel signals are mixed down and output at the
single surround back speaker by configuring the
"Surround Back" setting (page 76).
For 5.1-channel speaker layout, surround back left and
right channel signals are output at the surround left and
right speakers by configuring the "Surround Back" setting
(page 76).
Subwoofer (SW)
The use of a subwoofer with a built-in amplifier, such as
the Yamaha Active Servo Processing Subwoofer System,
is effective not only for reinforcing bass frequencies from
any or all channels, but also for reproducing the high
fidelity sound of the LFE (low-frequency effect) channel
included in bitstreams and multi-channel PCM sources.
The position of the subwoofer is not so critical, because
low bass sounds are not highly directional. But it is better
to place the subwoofer near the front speakers. Turn it
slightly toward the center of the room to reduce wall
reflections.
For other speaker combinations
You can enjoy multi-channel sources with sound field
programs by using a speaker combination other than
the 7.1/6.1/5.1-channel speaker combinations.
Use the automatic setup feature (page 30) or set the
"Speaker" parameters (page 76). to output the surround
sounds at the connected speakers.
■ Presence left and right speakers (PL and
PR)
The presence speakers supplement the sound from the front
speakers with extra ambient effects produced by the sound
field programs (page 40). We recommend that you use the
presence speakers especially for the CINEMA DSP sound
field programs. To use the presence speakers, connect the
speakers to SP1 speaker terminals and then set "Front
Presence" to "Yes" (page 76).
